(rIRAEtD, OF NASHUA, NEW HAMPSHIRE; SAID HENRY` GIRARD ASSIGNOR T SAID NAPOLEON GIARD TABLE CONSTRUCTION Application filed March 14, 1929. Serialz No. 347,005.

The present invention relates to improvements in the construction of tables having extensible top sections.

An important obj ect of the invention is the provision of a support slide whereby the extensible top sections of a table may be conveniently and noiselessly adjusted.

A further object of the invention is the provision of a table embodying an adjustable support slide construction designed to operate smoothly and without obstruction.

Another object of the invention is the provision of a table having adjustable top sections constructed so that the complementary bars forming the iexible portion of the top will be attached to a flexible connecting member in a novel manner designed to obviate distortion of the complementary bars.

Still another object of the invention is to improve the general construction of tables of the above character so as to simplify the construction thereof and improve the operation of the movable elements.

Other objects and advantages of the invention will become apparent as the description progresses.

In the accompanying drawing forming a part of this specification and in which like reference characters are employed to designate corresponding parts throughout the same:

Figure 1 is a perspective view of the improved table showing the top sections in retracted positions,

Figure 2 is a similar view showing the top sections in extended positions,

Figure 3 is a bottom plan view of the table,

Figure 4 is an enlarged transverse section taken on the line 4 4 of Figure 3,

Figure 5 is an enlarged fragmentary longitudinal section through the table,

Figure 6 is a longitudinal section taken on the line 6 6 of Figure 5, and

Figure 7 is a section taken on the line 7 7 of Figure 5.

Referring to the drawing, wherein for the purpose of illustration is shown a preferred embodiment of the invention, the numeral 10 generally designates a rigid table frame supportedV on'legs 11 and embodying. longitudi-` nal side rails 12. Rigidly supported in a transverse position on the frame is a fixed top section 13 disposed centrally between a pair of horizontally v and longitudinally.adjusta` ble top sections 14.

The movable or adjustable top. sections 14 embody a rigid portion 15 and an inner flex-i` ble; portion 16. The united portions15 and 16are mounted on the frame so as to. slide -60 between the framey side rails 12, thefrigid por-V tion being' limited to movement in a hori-` zontal plane while the flexible portion is arranged to roll about a pair of guide rollers 17 when the top sections are retracted:

An essential feature of the present invention resides in the provision of suitable slide Y structures adapted to adjnstably support each section and arranged adjacent each side of the section, as shown to advantage in Flig- "Y ure 3. To accommodate the slide construction, theinner surface 0f each framerail 12y is formedY with a longitudinally directed slot 18l disposed between the centre and outer endY Vof the rail, as shown in Figure 6. Attached Y to the under side of the rigid portion of each top section 14 are interior rails 19 mounted'. parallel with the frame rails and spaced inwardly therefrom. Each of the rails 19, care, ried by the top sections, is formedwith a longitudinal groove 20 arranged adj aeent the outer jend of the rail.- Adjacent their inner ends,the rails 19 support channel shaped .brackets 21 having the web portion secured to the inner face'of the rail and 'the flanges 85 extending laterally outward therefrom. A complementary lchannel shaped bracket 22 is secured to the inner face ofthe frame rail 12 adjacent the outer end thereof, this bracket being disposed in horizontal alignment with and diagonallyA opposedto the bracket 21. Slidably positioned between the cooperating rail `19 and the frame rail 12 is a longitudinal; slide bar 23 of elongated rectangular crossvg section formed to slide vwithin theV guide brackets'21 and 22. Adjacent itsy forwardv end, the. slide bar 23 carries ka lateral, out,- wardly projecting tongue 24 disposed to slidv ably project within the longitudinalegroove 1.90

18. At the opposed end, the slide bar carries posed to uide the slide bars and retain the a laterally and inwardly projecting tongue same in a orizontal plane.

25 arranged to slidably project within the longitudinal groove 20. Adjacent its outer end, the slide bar 23 carries an angular bracket 23 having one leg attached to the lower edge of the slide and formed so that an angular upright leg will be bent to slidably embrace the lower edge portion of the rail 19. This slide construction will permit easy and unrestricted adjustment of the extensible top sections within their limited movements.

The flexible portion 16 of each top section is composed of a plurality of longitudinal"V slats or bars 26 arranged transversely and united by a pair of longitudinal flexible strips 27, preferably formed of canvas or similar material. The forward ends of the canvas strips 27 are attached to the inner end portion of the rigid portion l5 so as to connect the flexible portion therewith. Heretofore, the flexible strips 27 have been connected to the slats 26 by placing the strips in contact with the under side of the slats and attaching the same thereto through the medium of an auxiliary connecting strip which was nailed or otherwise connected with the slat. rlhis construction was found objectionable in that the slats and connecting strips, being usually formed of wood, became disconnected due to the distortion or warping of the attached members. In the present construction, the slats 26 are of greater thickness and have relatively narrow slots formed therethrough designed to accommodate the canvas strips 27 which are then connected to the slots by tacks 28 or similar securingelements. Thus, the slats are composed of a unitary bar of wood which, if distorted, will have a uniform distortion throughout its length.

It is to be understood that the form of our invention herein shown and described is to be taken as a preferred example of the same, and that various changes as tothe shape, size, and arrangement of parts may be resorted towithout departing from the spirit of the invention or the scope of the subjoined claim.

Having thus described our invention, we claim:

In a table including a stationary support frame and a slidably adjustable top section, a

pair of slide bars disposed longitudinally between the rails of the frame and adjustable top section, a tongue attached to and projecting outwardly from the forward portion of each slide bar and projecting within a longitudinal guide groove in the railof the table frame, a complementary tongue formed adjacent the outer ends of the slide bars and projecting inwardly to engage longitudinal grooves formed in the rails attached to the slidable top section, and guide brackets attached in diagonally opposed positions to the rails of the table frame and top section dis In witness whereof we have hereunto set our hands.
